Question about Kirby G4 Bagged Upright Vacuum

1 Answer

I had problems replacing the fan on my KirbyG4 but with the help of this site was finally able to do so. When I put it all back together and turned on, the motor was very weak and then stopped and I smell something burning. This repeats every time I turn it on. Could I have burned up the motor while replacing the fan? The motor seemed fine before I started the fan replacement. I am the grandmother who posted yesterday.

    The beater bar is clean and rolls smoothly . Last night I removed the bar attachment, stuck a screwdriver into the switch which is on the front and even without the attachment, the motor was very weak. This made me conclude that the attachment and roller are not related to my problem. Since my motor was fine before I changed the fan, I think I must have damaged it. Can't decide whether to continue trying to fix. If I have to replace the motor I think I will just ditch. Any thoughts anyone?

There are a couple of possibilities here. First, I hope you made sure the new fan spun freely after installation, if so, and if you re-installed the rest of the parts correctly, you may have the belt installation crank on the front of the agitator housing in the up position yet. This is when you've installed the belt over the motor spindle. After that you need to continue cranking the assembly on the front until it's all the way down. That releases the belt so it can run freely and turn the brush. If it's still in the up position, it has the belt locked and the spindle will rub against the belt making the smell and smoke. Also if you closed the metal bottom plate and caught the belt under it when you finished the installation, that will also keep the belt from turning with the brush.

SOURCE: belt burning

the beater bar probably needs to be removed & cleaned. the shaft & bearings get bound up with hair, string, etc.. with the belt off the bar, it should spin fairly easily. if it's hard to turn,(belt off) then it's bound up.

SOURCE: burning smell

Unlock the sweeper brushes and take them out. on each end is a cup bearing and should be free of debris.
then check around and under the belt and likely there is debris wrapped around it.
the post is getting hot as your pulling too much of a load.
though if it continues the motor may have a bad set of motor brushes (inside the motor) or bad wiring (kinda unlikely).

How to fix a fan that goes off when put on higher option


That depends on whether the problem is a bad high-speed contact in the switch or an open winding in the motor. It's more likely to be a switch problem. In the best case, you can spray contact cleaner into the switch and it will work. Otherwise, you may have to replace it.

If you are really handy, you can take the switch apart (you may have to drill out a couple of rivets), polish the contacts, then put it together with some small screws and nuts - probably #2 size. If you do this I strongly recommend using a thread locking compound on the screws so the switch doesn't fall apart while the fan is running. If you can find replacement rivets in that size, that's a better way to go. Some fan switches are glued together or snap together; you'll have to examine yours to see what you have.

The motor on my carpet tool (beater brush) stopped running yesterday. The main vacuum still works, but the switch for the carpet tool just clicks and doesn't turn it on.


Knowing the model would help.
Possible problems:
Broken or disconnected wire in hose, connections, power nozzle.
Hose needs replaced. Check all connections for discoloration and cracked supports. Have power nozzle checked at a vacuum shop. Depending on the model, take it to an authorized Aerus Electrolux store for this.
Bad power nozzle motor Needs replaced.
Bad switch. Take the whole machine in for thorough check and repair..

Brushes do not spin


The manual suggests cleaning the filter screen near the brush assembly. This is located on the bottom of the unit. In cleaning this it did not successfully help. I then proceeded to take the cover (blue) off the motor an brush drive and worked my way to the gear assembly. This is where I found the actually problem.

The problem: The brushes are driven by a turbine wheel operated with suction from the vacuum. In my unit the turbine and bearings became loose or slipped to the point that the worm gear lost contact with the additional gears that drive the brush. When resetting the assembly so that ample contact is established the unit began to operate fine.

This can be complicated to explain and illustrate therefore taking the unit in for repair is recommended. If you are confident in repairing the unit yourself then go for it.

Kirby Heritage 2 fan replacement


Take the bag asm. and handle off. Then remove the plastic strip covering the switch, remove the screw there, remove the 3 screws on the housing, turn it over and loosen the screw near the back, the housing should come off. Then remove the screws on the back of the fan casing. You shouild be able to get to the fan, hold the fan and turn the spindle to the right to take off. If it would turn off, then you may have to lock the armature so it can't turn to move it. Then re-asemble in reverse.
